I have an unlocked Nokia E71, but my understanding is that ANY GSM phone will do, as long as it works on AT&T. You can buy a cheap Nokia pay-as-you-go phone for about $10 that will work. You need to pull the SIM card from your iPhone and plug it into the non-iPhone. Wait some time, make a couple test phone calls to ensure it's working.

AT&T knows what phone you're using (model wise) and will allow or block certain services appropriately (such as MMS messaging). The hacked carrier profile which enables tethering and MMS also disables the model reporting agent, so the iPhone no longer updates AT&T as to what model of phone it is.

The idea is that by using the non-iPhone, AT&T will update what it thinks you are using to be a non-iPhone. At that point, you can then plug the SIM back into the iPhone and your MMS messages will go through. How do you know what that point in time is? Since my non-iPhone supports MMS as well, I kept trying to send an MMS until it went through. That's when you know.

And now my iPhone tethers, does MMS, and my Visual Voicemail works.

Thanks for the VVM tip!

thats what my buddy told me to do too, but he also said that at&t is re-locking him out every few days. I don't feel its worth it to go through that every few days when i very RARELY send MMS' and I'm worried that at&t thinking I have a different phone will screw up me upgrading to a 3GS next week. But thanks for the info, I'm sure it will help others!
